 In this work, we propose a new directed digital signature scheme over a group ring whose security relies on the hardness of the discrete logarithm problem and the factorization search problem. This scheme is efficient as it requires very few…

Batteries play an important role in the performance enhancement of power grids including renewable energy systems. In order to attain the rated service life and the longest possible run time of a battery, it is necessary to be monitored and…
